1 Hera: cost effective spectrometer for lighting measurements The Hera Series spectrometers is ideal for LED measurements where ease of use, stability, performance and price are key factors. Available in various spectral ranges. VIS spectrometers ranging from 380 to 780nm (Hera 01) and 360 to 830nm (Hera 02). A UV spectrometer with a range from 190 to 435nm (Hera 03) and UV-NIR with a range of 200 to 1100nm (Hera 04).
2 Highlights
For measurements of light sources Admesy offers a range of integrating spheres which can be connected through M8 fiber connections. A fixed position fiber connector has been developed to connect the optical fiber in a fixed and uniform way from calibration to final use. Due to this fixed position measurement results are more stable. Furthermore, the Hera series is available in a variety of optical systems: 5, 10 or 20mm 2 collimating lens or a 1cm cosine corrector.

3 Speed & ease of use
4 Hera general specifications
Admesy strongly believes in developing and manufacturing devices where ease of use and speed are key factors. In order to achieve these aspects, Admesy considers the following aspects of spectrometers to be taken care of.
Hera types 01-04 Non linearity Spectral resolution Measurement parameters Data processing time Integration time Interfaces
Wavelength calibration Dark current Linearity Absolute calibration
Size (HxWxD) Weight Power consumption Operating temperature
Calculations and compensations are done in a staggering 14ms. All this is possible due to the high speed processor inside the Hera combined with algorithms developed for this specific device. In production processes, no external calculation power is needed from computers. Data can be used directly in production settings without any delay of processing data afterwards. This saves time and processing power of the operating system of a production line. When for example setting the integration time to 10ms, full calibrated spectral data is processed within 24ms. This includes transferring data through high speed USB. This makes the Hera series an ideal LED sorting device where speeds up to 50 LEDs per second can be achieved.
